'be described Vmore in detail. The sidewalls i and I7. Reciprocallymounted on thesel ftra'ck and v4guide members? is lthe formery block 18which is; 1in `the form of a ybifurcated on z"theoriiier block andbetween the legs rearward end of the 'driving Vmember '19 lextendsvbeyond the `rearward extremity of `the former block flS, 4and carries alaterally lprojectinglug 20 and ya depending-portion 21. In achannelinthe rear portionV ofthe former 'block 18 `is a plunger v22 'held'outivardly -by -a coiled spr-ing'l. The ,plunger 2Q. llies inthe pathofthelu'g 20. @pera'bly connecting the depending'member 21 yandv ftheupwardly extending arm of the fforrn? ing bell `crank '5 is alink 25.yThe extremity ofthe vertically extending arm of i'the' "bell cran`k5is-disposed in proximity 'to lthe former block 18, and carries aA'single'gear it o tooth 26 designed to have operative engagement withthe former block within a notch which is provided in its lower side, asbest seen in Fig. 2. By virtue of the connece tions just described, asthe bell crank 5 is swung forwardly by the downward movement of the link10, the tooth 26 will engage the forward side of the notch of the formerblock and slide the block forwardly, while the driving member 19 is alsocarried forwardly by virtue of its connection with the bell crank 5through link 25. The initial movement of the bell crank 5 which bringsthe gear tooth 26 against the forward wall of the notch in the formerblock, also brings the lug 2O closer to the end of the plunger 22. Asthe former block is carried forward by the swinging movement of the bellcrank 5, it ultimately reaches a point where the tooth 26 will bedisengaged from the notch in the block, whereupon the further movementof the block, as well as the movement of the driver, is accomplished byvirtue of the engagement of the lug 2O against the plunger 22, and theoperative connection of the driver with the bell crank by means of link25. ln this fashion the latter portion of the movement of the formerblock is accomplished through the cushion connection furnished byplunger 22 and spring 24.-. Tilhen the former block reaches its limit ofmovement, which is determined by the thickness of the work with which itis .brought Vinto contact, the driver will continue its downwardmovement, which is permitted by this yielding connection afforded byspring 2e'. The driver is provided with lugs 13 which move in grooves 23in the former block. 0n the rearward .movement of the driver, these lugscome up against the rear ends of the grooves 23 and move the formerblock rearwardly to the point where the notch on its lower portion is inposition for engagement by the tooth 26.

Below the former block and in line with the driver, is disposed amandrel 27, which is fulcrumed at 2S, and has an upwardly directed frontarm 29 and an upwardly directed rear arm 39. rlhe rear arm 30 isdisposed in the path of the cross connecting member 13 carried on theformer block, so that the latter 'will ride over the arm 307 swinging itdownwardly and swinging the forward end 29 of the mandrel member upbetween the legs of the former block and into the plane of the driver.The forward lower portion of the driver is formed as a rearwardlysloping inclined plane which is adapted to engage the forward end 29 ofthe mandrel member and cam it downwardly out of the path of the driverwhen the former block is moved forwardly a distance sufficient todisengage the cross connecting member 18L from the rearward end of themandrel member.

Referring now to Fig. 3, it will be understood that the wire feeding arm15 carries at its outer or free end a detent member 31 adapted to engagewire fed from the spool 12, so as to carry the wire as the arm swingsaway from the spool, which it does under the influence of a spring 32.rl`he means for controlling the movement of the wire feeding arm 15includes a short bearing arm 34 extending leftwaidly from the wirefeeding arm and carrying at its extremity an antifriction kroller 35.rlhis roller is adapted to engage the lateral margin of the former block18. This Vmargin of the former block 18 is formed with an offset 36which permits the arm 15 to swing leftwardly as the former block isretracted, and then. presses the arm 15 toward the right as the formerblock moves downwardly. ll`he wire thus fed leftwardly by movement ofthe arm 15 is held against rightward movement by the detent 37, andpasses through the wire channel 38 in back of the forward end 29 of themandrel, in which position a section is sheared off by the former blockupon its downward movement, all in the customary fashion.

Referring now to Figs. 1, 2 and 5, it will be seen that a cover plate39, screwed to the guide members 1G and 16, covers the former block andthe driver, and said cover plate has a rightwardly extending portion 39awhich covers the wire-feeding arm 15. ln this portion 39a is rotatablymounted a pin l0 which carries at its upper extremity above the member392L a yoke Ll1, and at its lower extremity below the member 39Et an arm42. This arm extends leftwardly, as best seen in Figs. 1 and 3, to apoint where it is engaged by a pivoted crotch member lll rotatablymounted on the upwardly en tending arm of the button feeding bell crank8. The table member 11 is suitably apertured to permit the passage ofthe upper extremity of the said bell crank member, and as seen iii-F ig.5 the cover portion 39'd1 is shaped to accommodate its forward andrearward oscillatory movement. Pivotally mounted in the yoke l1 is abutton-feeding linger 45, the arrangement being such that the feedingfinger may be swung downL wardly into the operative position sh wn infull lines in 1, or upwardly into the inoperative position shown indotted lines. A tension member 46 (see Figs. 1 and 5). which is pivotedat 46a and urged downwardly by a spring 461, is adapted to contact withthe upper surface of the button feeding finger so as to exert a yieldingpressure upon the same in a downwarr direction. rlhe tension member i6has a lower bearing edge, which engages the button feeding linger,formed with considerable length to accommodate movement of the buttonfeeding nger. The tension inem- -ber 46 carries a lateral projection461which may ".be'engaged by the fingerof the operator to lift thetension ymember away from 4thebutton feeding finger toenable the llatterto be' swung upto the position illustrated inidot and dash linesin Fig. 1. The forward extremity of the button feeding' linger is deflecteddownwardly atan angle to its body portion to provide the button engagingyportion 45L which 'is suitably shaped at its-lower margin to engage abutton. Y

A button'tube 47 of conventional forni=is removably mounted on 'thecover portion 39 in pedestal member-s 48-and 49, the upper lowerextremity the tube abuts a button guide plate 5l which first slopesdownwardly from the end of the tube on a plane substantially parallelwith the r`tube and then changes its angle of slopeso as'ltocontinuesubstantially parallel withfthe former block and driver, in whichposition it lies directly above and forms a cover 'for-them. The buttonguiding plate is provided with a button slot designated by the numeral52 which registers Awith-the Yeye receiving channel of the tube 47 atits upper extremity, and for a portion ofits length adjacent the lowerportion of the plate lies in alinement with the groove 19L ofthe driver.The slot at the lower extremity ofthe 'tube A47 lies on a radiusrelative to the pin '40 equalto the length of the button feeding finger45, and the adjacent portion of 'the slot 52 is also formedsubstantially on the same radius, so that the slot takes a yrightwardlyslanting or arcuate directionas illustrated in Fig. l. At the pointwhere theslot Vcomes into alinement with the slot 19.31 of the driver,it changes its direction to the left Vso that it leaves the'said radiusand lies out of the reach of the button feeding "finger 45. A spring`finger 54 is adapted 'to retain buttons in the tube 47 from slidinginto `the slot 52. Depending from the button feeding finger 45 andpivotally secured thereto, is an elevating pallet 55 which is formed soas to permit its oscillation rearwardly on its pivot, but not forwardly.lv'lounted on the cover portion 391L in'coperative relationship with thepallet member 55, is a cam member' sloping upwardly from its forwardedge. i

lBy virtue of this' arrangement of parts,

whenever the button feeding bell crank N8 isV 'oscillated 'by the'meansheretoforev described,

varm I5 iiiithe manner abovedescribed.

fit will rrst :swing rearwardly, f swinging the l'arm-'42 which iiituriirotates'thepin 40v and swings the button feeding vfinger 45 rear-:wardly In the rearward movement of the button 'feedingifingen thepallet member 55 coinesiinto Contact Awith'the cam member 56,

Iand rides up the sloping face of the latter,

'thereby elevatingfthe free extremity of the button Y feeding finger. Inthis movement, thebutton feeding finger is held underyieldingtensioiifbythetension member 46, which permits its upward 'aswelll as its rearward movement. linien, in the course of therearwardfmovement ofthe button feeding linger,

the pallet member 55 reaches the rearward extremity of the cam member56, it drops olf of the-saine, thereby directly lowering thefree'extremi'ty of the button feeding finger.

rFhisbrings the button engaging portion '45a down onftop of and intooperative engagement with the lowermost button which isretained bythespring finger 54, the tension member @46 operatingfthus to force thebut- -ton feeding finger downwardly into engage- 'ment with the button.Thisbeing accom- Aplisliedl at the end of the rearward movementoftliefbell crank 8,"the latter then rocks forwardly, swinging thefree'end ofthe button feeding finger forwardly through theinstrumentality ofthe connections just described. Ars the button'feeding finger moves for- `wardly, fitfcarrie's the buttonl with whichit ifs iinlengagement out from under the spring Eiinger54 and down theplate 5l, the eye of the button riding inthe slot 52, the pallet 55bein@w rocked rearwardl uion yen 'agement with the cam member 56 so asto permit the extremity ofthe button feeding finger rey.'in'aiiiing inengagement with the button. The button is carried forwardby thisinovement to the point -where its eye comes up against the extremity'ofthe mandrel member "29, `at which point the button guiding slotchanges fdir'ection, so that the further 'movement of the button feedingfingercar- 'riesit out ofthe path of tliebutton, as will fbeobvious fromFig. l. lThe rearward tip ofthe l=ineniberf45a, however,` is left inengagement with the button so as tosteady it in position to receivethe-staple wire. rlfhe wireis fed to the button by movement of-tlle tthe next depression-of the treadle, Vthe' former blockv movesIdownwardly in the manner above ldescri'bed'to shear olf the sectionofthe wire 'andlto bend it about the mandrel 29 to form the staple jinthe customary fashion. The ldri-ver 19 then moves `downwardly to engagethe button and staple and carry it forward and set it in the worli inthe well f known manner. It 'willbe observed that by Vthe artcu-lationofthe parts', the button feeding 'linger frnoves rearwardly as theformer and dr-ivermove forwardly. The slot 19EL in the driver is formedto accommodat-ethereye nur:

ot the button which is brought down by the button feeding finger whilethe driver is moving rearwardly.

in order to prevent the feed of wire when o button is ted to thestapling position, 1 ro. ide on the cover portion 89a a stop memr 5Swhich is spring-pressed upwardly so at its upper extremity will lie inthe path he lower face oi' the button feeding iinger 'W hen projecteddownwardly, the lower .i/'treinity oi the stop member 58 is adapted uolie in the path of the wire feeding arm 15 where it may engage anabutment member 59. lli/lien, in the forward movement ot' the button'feeding linger 4:5, the button engaging member 15a is raised on top ot'a button, the arm will be held out of contact with the upper extremityof the stop member 58. Consequently, the latter will not be projectedinto the path of the wire feeding arm l5. it, however, no button isengaged by the button engaging` portion 15 of the button feeding iinger,the latter will be permitted to drop into engagement with the upperextremity of the stop member 58, so as to press the latter downwardlyinto the path of the wire Vfeeding arm 15 to ciectively hold the latteragainst feeding operation.

From he foregoing description of the construction and operation of mydevice, it will be seen that it possesses very distinct advantagesarising from the construction and articulation of the various parts. Allcams are obviated by the arrangement whereby the movement of the mandreland of the wire feedingI` arm are controlled directly by the formerblock. rl`he method of actuating the former block provides a positivedriving connection to effect the wire severing and form ing operation,and a cushioned or yielding pressure driving connection for the block asit is carried forwardly to bring the staple into position against thework, said yieldable driving connection permitting the tormer toaccommodate its forward movement to work of dierent thicknesses. rEhearrangement of the button feeding iinger permits its being thrownentirely away from the button stapling position, to the positionindicated in dot and dash lines in Fig. 1, which permits the machine tobe used to staple an odd button, viz., one of a sort differing fromthose in the tube, without requiring the removal of the tube from themachine or the insertion ot the odd button in the tube and the feedingout of the other buttons below it. rlfhe relative disposal of the buttonfeeding linger, the tube and the forming and driving mechanism permitsthe button to be carried to the driving position without interference'from the nger, and at the same time greatly reduces the eX- tent otmovement of the various parts of the machine.

intentes 1t is to be observed further that this con struction requiresbut very `few parts, and that all. of the parts may be made of such sizeas to secure great strength and insure certainty ot operation. rTheworking parts are all well housed and protected and the machine as awhole is very compact.
